each end. which, although shrouded, were
finished to perfection in a gear-cutter and

Coridad. was constructed by Ross. That It's

COMPREHENSIVE attention may be directed 10
the fact that the diameter of it's wrought rol!

excess of that possessed by the rollers tneni-
selves in, perhaps, one-haf OF all louisiana
steam mills.
Few fve-roller mills exist on the lslano'
certainly none were encountered on TINS jour
new. Multiple crushing is, however, common
to all houses of the frst-class, being perform
ed by two three roll affairs, each with engine
and through gearing entirely It's own. Ihese
mills while often found directly In line Win

their motors being then placed respectively
upon opposite sides of the apparatus, are RE-
ouently mounted side by side, with both en-
gines between for control by a single. attend
ant, as exampled at the Tolado estate, near
Havana: or, instead, at right angles ana
sometimes far distant the one from the otnef'
as at Central San Limo, being III these cases
always SO connected by cross carriers asUo ao-
NIT of single crushing on each, If the cane sup
ply becomes excessively rapid, or on elther' III
cases of accident to the other. This arrange
ment, with duplication Of motors, possesses
the further advantage, as enjoyed at Des
Lignes, on the Teche, of permitting the re-
lative speed of the two mills being altered at
will.
OF two mills, arranged for multiplication
OF pressures, the stronger is most often plac-
ed first, because the initial, structural DIS
indignation of the cane, performed win SO
small an expenditure of power when made a
cutting or semi-cutting operations AS by the
Fiske Shredder, is believed to demand, when
accomplished by the crushing of rollers, SO
much more of this and of consequent strength
in the machine for its safety, than can afford
useful effect if consumed upon bagasse.
The most interesting mill of all is that
probably of the Ingenio Carolina, with eight
rolls, which, mounted in pairs somewhat az
ter the. manner of the Salisbury mill, is de-
void of intermediate carriers and as elemental
nv in it's gearing as our own simplest i've roll
arrangement. The rolls, placed uniformly With
out dip or inclination, besides being through
out OF a size, namely, sixty-slx by thirty
three inches, with journals fourteen by
twenty-one inches, possess, all OF them, the
same peripheral speed of eighteen to twenty
feet per minute, and have shown a capacity
at times of thirty long tons per hour, with an
extraction ranging from sixty-eight to SIXTY
nine per cent-rather Indifferent work tor so
costly q machine, as it might appear, except
for the 338-1-3 pounds of net marketable
sugar secured for each such ton handled, on
an entire crop.
The mills are so closely erected'to one an
other that return plates or cane knives, be-
tween them, answer to conduct the bagasse
from the one to the next set of rolls, these
knives being so finely perforated as to admit
of bagasse saturation with steam, exhaust or
direct, passed through their bodies, as II
through infinitely pierced pipes. The Jour
mills are alike driven by their lower roll
shafts. While beam engines of no particular
merit are attached almost exclusively to Gu
bian mills, this is aetuated by a duplex or
double cylinder, non-condensing, simple ex-
pansion affair. of adjustable cutoff. A horI-
zontal engine may also be noted at Constan'
tia connected with one Of it's three extraordl-
narily- massive mills.
In cost. these heavy mills have, many OF
them. rivaled the price readily to be realized
for the best of our Louisiana plantations COM
